ABSTRACT:
The invention relates to a system that uses human readable microfilm to store information and retrieve that information for later use in a computer. The microfilm is put into a Computer Input Microfilm (CIM) Reader that scans the film and converts the characters or text in the image into computer codes. An Optical Character Recognition algorithm is used to identify the text character and the CIM Reader converts that character into a computer code.
